<p>This element lets you output sound using the Open Sound System (OSS).</p>
<p>Note that you should almost always use generic audio conversion elements
like audioconvert and audioresample in front of an audiosink to make sure
your pipeline works under all circumstances (those conversion elements will
act in passthrough-mode if no conversion is necessary).</p>
